ART Teknika has released a new convolution reverb app with over 100 impulse response files included. The app allows to import your own IR files (below there are several links where you can get if free).
iConvolver is Aubiobus and IAA compatible so it is easy to implement it into your sound chain.

iConvolver - Impulse Response ...

iConvolver is an app for conveniently utilizing convolution reverb on an iOS device.

Convolution is an effect that adds sampled reverberative properties to a sound to recreate the original properties of that sound. The data of these reverberative properties are called the Impulse Response(IR), and can record the properties of not only acoustic space but also from such things as hardware and speakers. By recording the properties of reverberation from acoustic spaces such as halls and studios, high grade hardware reverb, spring reverb, speaker cabinets and microphones, etc. to Impulse Response files, they can be reproduced in iConvolver.

As iConvolver comes with several Impulse Response files included, you can immediately test out those sounds.

***Main features***
+ Equipped with an original convolution engine.
+ Actualization of zero latency.
+ Compatible with external Impulse Response files(WAV/AIFF formats(1ch,2ch,4ch)). Open In is compatible with Zip files, and can extract Zip files as well. (Not compatible with password-protected Zip files)
+ Equipped with low pass and high pass filters for adjusting reverb sound.
+ Can be used in combination with other apps compatible with Audiobus and Inter-App Audio. Standalone operation also possible.
+ A universal app that can be used with both iPhone/iPad.
+ Comes with several original IR files(over 100) included.

***Main uses***
For recreating reverb, acoustic space, speaker cabinet sound, etc.

***Regarding hardware compatibility***
iConvolver by its nature requires a relatively heavy CPU load.
Devices with 64 bit CPU recommended.
iPhone 6 and above, iPad Air 2 and above are especially recommended.
By increasing the audio buffer size, and shortening the utilized IR, the memory load can be lessened.

Where to find IR files?

Here is a collection of great places where you can download free impulse responses from hi-end hardware reverbs to weird halls and strange things like dustbin:

Also if you have Logic Pro X you can find IR files folder //Library/Audio/Impulse Responses and you’ll find many files open in iConvolver or similar apps without any problems. BTW, Logic Pro has one of the best Impulse Response file libraries (there is unconfirmed information that they made a deal with Audio Ease – developer of $500 Altiverb convolution reverb plugin to use some of their files).

How to make IR file?

You can create an IR files by running sinesweep file through the reverb device or mic it in a space and deconvolve it with software like Voxengo Deconvolver – http://www.voxengo.com/product/deconvolver/

AltiSpace - Convolution Reverb

The realistic sound of famous reverb gears in your iPad and iPhone. Includes a large built-in library of the highest quality reverb impulses taken from the most known and outstanding devices and possibility to upload your own impulses of reverb spaces. Intuitive and compact user interface for maximum ease and efficiency.

You can use this application together with Inter-App Audio hosts (like a DAW, Recorders or Audio file managers) or with Audiobus for adding studio quality reverberation effects to the sound of other music applications or pre-recorded tracks.

AltiSpace can also be used with external audio interfaces for real-time sound processing. Suitable for live performance or in the studio together with other equipment.

What is the convolution reverb?

Briefly, convolution reverb is based on a process that digitally 'captures' the reverb characteristics of another reverb effects unit or the reverb response of a real acoustic space. It is based on the mathematical convolution operation, and uses a pre-recorded audio sample of the impulse response of the device or space being modeled. The process of convolution multiplies each sample of the audio to be processed (reverberated) with the samples in the impulse response file.

Main features:

● More than 400 factory presets from 24 actual reverb devices.
● High-quality and fast convolution algorithm with 64 bit operations.
● Low latency for comfortable using at live performance.
● Wide range of reverberation types such as plates, springs, halls, rooms, etc.
● Preset hotkeys with possibility to save current sample and all its parameters.
● Convenient choice sample by device name, reverb type or in complete list.
● All processing parameters are stored for each sample.
● Pre/post parametric equalizer with cut-off filters.
● Possibility to construct the envelope (like ADSR) for device sample.
● Changing offset from beginning of sample (start time of sample).
● Adjusting stereo width and modulation for reverb output.
● Additional mode 'Reverb only output' for use with DAW and mixing consoles.
● Possibility to upload additional samples in different audio formats.
● Uploading samples thru Web access, audio clipboard, from another app or thru iTunes.
● Detailed application description with an overview of famous reverb equipment.
● Different color schemes available for the user interface.

Compatibility:

● Inter-App audio compatible.
● Supports Audiobus in Effect, Input or Output slots.
● Supports Audiobus "State Saving" feature.

Requirements:

Third generation of iPad or fifth generation of iPhone and higher is recommended (especially with Inter-app audio and Audiobus).

Mobile Convolution Reverb

LiquidSonics Mobile Convolution is a true-stereo reverb processor for use with Audiobus and Inter-App Audio hosts. It allows impulse responses to be stretched, cropped and envelopes to be applied for shaping the sound of a reverb in a very natural and musical way. A configurable pre-delay provides the ability to push a reverb back into a sound-field or to creatively add rhythmic delay effects. The IR mirror mode adds further creative potential for ghostly reversed reverb effects with natural decays, or reverbs that gather into a crescendo.

With the high, low and peaking audio filters you can make adjustments to a space's frequency spectrum, rolling off lows, highs or accentuating specific frequencies of interest with the variable gain and width control of the peak filter.

Stereo and true stereo impulse responses up to 90 seconds long can be loaded with very low input/output delay (latency). Mobile Convolution uses the same great LiquidSonics convolution engine that powers the desktop plug-ins which are used in both home and professional studios worldwide every day.

A collection of true stereo impulse responses is provided, and external impulse responses can be added quickly and easily via Open-In... support in apps like Mail, Safari and Dropbox, downloaded directly from within the app or added via iTunes File Sharing.

Internal preset save and recall is provided, as well as Audiobus state-save recall support.

Also don’t forget that Auria has excellent convolution reverb plugin built-in.
